"In order to advance research and development on life stage challenges (e.g. influences on timing of dementia onset, effects of fetal exposure in adolescence), we will hold a joint workshop between researchers of the University of Bristol related to the ALSPAC （The Avon Longitudinal Study of Parents and Children）which is funded by the Medical Research Council and the Wellcome Trust, and 11 Japanese researchers involved in projects related to epidemiological cohorts and biobanks supported by AMED. During the workshop, we will introduce our projects, discuss challenges of utilizing big data and international comparison between Japan and the UK, and investigate potential for international collaborative research."
